This is armored Sharp animals

1. hedgehog


Who does not know and recognize the hedgehog, the animal's body is entirely covered with sharp spikes 63-91 cm long which makes it very difficult to attack by predators or other animals.

Hedgehog is an animal that protects itself by relying on the thorns both when ready or not ready. Makes this animal is ranked first in this list.

2. Lion fish


Lion fish (Pterois antennata) is a poisonous fish that comes from the Indo-Pacific waters. These fish protects itself with a combination of sharp thorns on its body and the toxins contained in the body.

When exposed to the poison, it will be very fatal to living beings are exposed to toxic, even for humans.

3. Armadillo lizard


Armadillo lizards (Cordylus cataphractu) are animals that come from Africa and Madagascar. Animal skin is very hard and like thorns.

Armadillo lizard ball to protect himself by biting his body and his tail to form a loop as a defense system safe from predators.

4. pufferfish

First of all these fish will absorb the water around it to develop his body up to 2 times of the original, then this fish enforcing the thorns as a safeguard of ambush predators.

5. beaked


Beaked (Tachyglossus aculeatus) is a mammal of the rabbit whose entire body covered with spines. They live in the forests of Australia and Papua New Guinea.

Has a long-beaked snout and a large nail to facilitate them in exploring the land.

Beaked defense system is by its thorns thorns until 5000 and 2000 electric field sensors on his body, the defense was very strong and difficult to penetrate.

Can be seen beaked has ideal protection to protect itself from threats.

Physics in Daily Life



Physicists found the amazing detail of the universe, from the black hole radius to the subatomic particles that are all visible. What about on the outward appearance?


You may be surprised to discover the lack of explanation for many phenomena that occur in your daily life. Some of the most mysterious things may appear normal even in your eyes.

Bean

In the bowl of mixed nuts, Brazil nuts always seem to be at the top. This is known as the 'Brazil nut effect'. This phenomenon does seem unusual, but became one of the greatest mysteries of physics that has not been solved. Among the various items and ignoring gravity, the larger objects always on top.
Convection currents believed to play a role in the condensation of smaller particles. All of these possibilities contribute to the Brazil nut effect. But until now, no one and none of the computer simulations successfully explain it. In fact, physicists, astronomers and geologists to this day can not understand this phenomenon.

Foam

Washing, shaving, or drink soda or beer? When doing that, sometimes you can find the foam and we often get it. According to Douglas Durian professor of physics at UCLA, the foam is 95% air and 5% liquid. Gas in foam separating the liquid to form a matrix of tiny bubbles.
Unfortunately, until now there is no formula that can explain the nature of the foam. "Physics of foam have not been well understood," he said at the NASA Science.

Ice

Century and a half investigation could not determine why ice can make you fall. Scientists agree, a thin layer of liquid water on ice kelicinannya solid lead. However, until now there was no consensus on why it has a layer of ice.
Theorists argue, it arises as a result of contact with the surface which makes ice melt. You might expect there are those who blame, but until now, scientists have raised their hands for this.

Cereals

Cereals tend to congregate together or get out on the edge of the bowl. Scientists dubbed 'Cheerios effect'. This phenomenon also applies to anything that floats. Dominic Vella of Cambridge University and from Harvard University Laksminarayanan Mahadewan be the first to explain this.
According to them, this effect is the result of the geometry of the liquid surface. The surface tension makes the surface of the milk collected in the bowl because the water molecules are interested in milk glass, milk hollowed surface on the end of the bowl. The result, if it does not accumulate in the center, will be on the edge of the cereal bowl.

Magnet

Jearl Walker professor of physics from Cleveland State University explains, naturally magnetic field emanating from the electrical particles that make up atoms, mainly electrons. To understand the simple magnetism can still be done but not to the deeper.
Although physicists have 'quantum mechanic' who can accurately describe the behavior of particles, including magnetism, but intuitively, it is impossible to understand the true meaning of that theory. "It's just a feature of the universe and the mathematical explanations as an effort to complete the" homework "of nature and look for the answer," said Walker.

Static Electricity

Static shocks very mysterious. It is known, this happens when there is excessive negative or positive currents appear in the body and the shock when you touch something. Alternatively, static electricity can occur when the static electricity build up in something that you later touch. The cause is still unclear.
General explanation stated, the two objects hit bergesekkan electron in one atom of an object and make it an object to be too positive or negative. Both objects then electrocute each other. But why electrons flow from one object to another? It can never be explained.

Rainbow

Rainbow is formed from sunlight in drops of water in the atmosphere. These water drops act as a prism that separates light into component light and sends it to the 40-42 degree angle opposite the sun.
Scientifically, no longer a mysterious rainbow as an explanation of the rainbow has appeared since the advent of the 17th century physicist Isaac Newton. However, imagine how mystical rainbow before. In ancient Greece, for example, the rainbow is considered as a way to bridge the messenger of God created the Earth and sky.

1. Gorges Sianok

Sianok canyon located in the center of Bukittinggi, stretching from the South Tower Nagari Koto continue to the North, Nagari Sianok Six Tribes and ends at Palupuh length 15 km, a depth of 100 meters and 200 meters wide. Quiet Sianok canyon or valley is a beautiful valley, green and lush, didasarnya a tributary flowing sinuous trace cliff crevices with a colorful backdrop of Mount Merapi and the verdant Singgalang is a fascinating nature. The uniqueness is easily accessible canyon, a canyon in the center of the city that does not exist in other cities in the world. The natural beauty of the enchanting canyon Sianok always perpetuated by tourists to take photographs as well as for the painter's imagination. Surf trip through the canyon trail in the valley is an attractive recreation, if the journey continues keseberang canyon within 45 minutes you will arrive at the Tower as Nagari Nagari Koto from some of the leaders of Indonesia, among others: H.Agus Emil Salim and Salim.

2. Anai Valley

Anai Valley environment is admirable. Dense tropical forest is impressive and is a protected forest. Didasarnya Batang Anai river flows with the water is clear and visible a 40 meter high waterfall close to the highway.






3. Anai Resort Golf Course

Anai Resort is located 550 m above sea level. Is the best Golf Course in West Sumatra International status with 18 holes, designed by International Golf Course Designer Thomas and Perret. Various facilities are on-site bungalow like a natural swimming pool and restaurant.





4. Valley Harau

Is a nature reserve with a steep limestone hill with a height of 100 to 150 m, located 14 km from Payakumbuh. Here also found five waterfalls that pour out the water is always crystal clear. In this place are also available for camping facilities for youth and tourism activities around the nature reserve along the path. Planned nature reserve will be the first wildlife park outside Java.

Jabal (Mount) Magnetic been phenomenal


Inexhaustible natural phenomena in Medina and Mecca. Now, Jabal (Mount) Magnetic been phenomenal and much talked about umrah.Kelebihannya assembly, capable of driving a vehicle with a speed of 120 km per hour with a neutral gear position
His name is not as famous as the other historic sites in the holy city of Medina and Mecca, as Jabal Uhud, Baqi 'Jabal Rahmah, and others. But, lately, Jabal Magnet invited Arab and umrah pilgrims to come to feel the benefits.

A reporter trying to trace this mountain with merental taxi. Rates for this place depends on the nego with the driver. Typically 100 to 400 riyals. The location is pretty good from the City of Medina, about 40 km to the city of Tabuk. Jabal Magnet outside the forbidden regions, allowing free non-Muslim residents visit.

If seen by naked eye, it's really not much different from other regions, namely in the form of barren rock hills surrounding the city like a lot of Medinah. Only when the vehicle reached the highway between the hills, will feel there is an oddity.

For about 4 km long road in the hill area is believed to have thrust. The car will run at high speed away from the Jabal Magnet, although the car in neutral gear.

It is perceived co-author of two other congregations, and Rush Nursan Rashid. When the taxi we were riding towards the south, Jawahir, 42, taxi driver Kerawang, West Java, was admitted to be very heavy vehicles although not as uphill road terrain.

More and more, even he was forced to move to the position of the car into gear, because trouble moving up to speed only 15 to 20 miles per hour. In fact, the road conditions are not too steep, should the two gears, the cab is still strong.

Neutral gear, Cars 'Fueled' Steer clear of Jabal Magnet:
With a heavy rate, Jawahir sure there is the influence of magnets that hold the car's motion. Conversely, when the car turned toward the direction of Medina, a driver who has six years of living in this city claimed the taxi drove at high speed, although the gear in neutral position. More and higher vehicle speeds. In fact, only about 3 km, taxi speed is the figure of 120 km per hour.

Out of curiosity, the author nor Nursan, the assembly of the Maros it turns driving the vehicle. "Sure, it's a miracle. Period in a neutral position, vehicle speed can be up to 120 km per hour. There is certainly the thrust of the mountain, "Nursan pointed toward the mountains in the surrounding streets.

Rush Rashid also did not want to miss. Former racer drag race in Makassar, said a lot to know about the speed of the vehicle. When the car is driven towards the city of Tabuk, which is the direction to Magnt Jabal, he was only able to step on the gas up to speeds of 50 miles per hour. "This is my walk on was full, the sound again at the bottom.

Means we can not force, "he said. When the gear is returned to neutral position, the car slowly stopped. In contrast, when Rush tried to Medina with the neutral gear position, the needle is actually rotate the car kilometers to a point 120 miles per hour.

Indeed, field road to the City of Medina somewhat decreased, but with this condition unnatural acceleration of the car so quickly. In fact, the vehicle actually be higher, but did not dare Rush Nursan and then halt for not being able to control it.

There are no clear boundaries, starting from where the road has a magnetism that. But if it is felt, the influence of the magnet when the vehicle starts moving from the dam water which is not far from the run-up to the hill before the turn to Medina. After driving about five miles, the speed of the car began to decrease gradually, but the road is still declining. Finally, the car has a slow speed while in front of the dam water.

The same thing is felt when Kopertis Region IX Coordinator Prof Aminuddin Salle who also visited this place. He claimed to pay for a taxi to 400 riyals just because you're curious to know the unique place it is. "I just never heard of, so I take advantage of this opportunity to feel the thrust of the magnetic mountain. It turned out very well. Subhanallah, "said Aminuddin Salle.

Not known exactly what the relationship between the magnet with the vehicle. Until now there has been no research on the driving force of the magnet by an expert. "There is no research. It's also just word of mouth information to many people who are interested in playing here, "the story of Jawahir.

However, from some of the information developed in Medina, said the former Jabal Magnet discovered accidentally by a Bedouin Arab. At that time the Arabs is to stop his car because he wanted to urinate. But because it was dying, he turned off the car, but do not put the hand brake.

While enjoying a pee, he was surprised absurdly, the car is running its own and increasingly tight. "He tried to catch up, but of course did not work. And according to his story, his car was stopped only once strayed to the pile of sand next to the road, "said Jawahir.
